A 12-year old neutered male Yorkshire terrier dog was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of chronic intermittent diarrhea, vomiting, anorexia and weight loss of 2-months duration. On presentation, he was very cachexic and had ascites. Abnormal findings on a complete blood count and chemistry profile included mild anemia, leukocytosis, panhypoproteinemia, hypocholesterolemia, decreased blood urea nitrogen (BUN) and increased serum bile acids. Radiographic findings indicated microhepatica. Peritoneal fluid analysis was consistent with transudates (total protein < 2.5 g/dl, total nucleated cell count = 2,200/ul) and cytologic examination of the fluid revealed neoplastic lymphoblasts. From these findings hepatic dysfunction and protein-losing enteropathy were attributable to abdominal lymphoma. This case suggests that cytologic examination is important in diagnosing underlying diseases of ascites, even if it is transudative effusion.

Physical examination and surgical findings and symptoms are often inconsistent with magnetic resonance imaging (MRI) findings when diagnosing chronic ankle lateral ligament instability, and confirmed surgical findings are used as the gold standard in most clinical studies. Anterior drawer testing is considered unreliable because normal findings are highly variable, and its accuracy ranges from 50% to 100%. Furthermore, radiographic stress imaging, such as in anterior drawer stress view, is performed under manual stress or using a stress device, and its findings also vary widely and confuse when interpreting stress views. The average accuracy of MRI findings is around 85% (range, 66%~91.7%), and thus, cannot be used as a primary indicator for surgery. For patients with suspected lateral ankle ligament instability, based on symptoms and physical examination findings, MRI may be useful for identifying lesions in ankle joints and for differentiating them from other conditions.

Two female Yorkshire terrier was referred to Veterinary Medical Teaching Hospital, Seoul National University. In case 1, clinical signs were vomiting, anorexia and weight loss. Cystic intraabdominal mass was identified in radiographic and ultrasonographic examination. In case 2, clinical sign was abdominal distension. In radiographic and ultrasonographic examination, cellular ascites and bilateral intraabdominal masses next to kidneys were observed. Many clusters of glandular epithelial cells with anisocytosis, anisokaryosis, high N:C ratio coarse chromatin and prominent nucleoli were shown in cytologic examination of sanguineous ascites. In all two cases exploratory laparotomy was performed and enlarged ovaries were observed (Rt: 6$\times$5$\times$5 cm and Lt: 3$\times$2$\times$1 cm in case 1 and 3$\times$2$\times$1 cm bilaterally in case 2). After ovariohysterectomy histopathologic examinations were performed. Histopathologically the masses were diagnosed as ovarian adenocarcinoma and ovarian cystadenocarcinoma in case 1 and case 2, respectively. In both dogs no further chemotherapy was carried out. These two dogs had no gross evidence of tumor recurrence at the time of 3 months after tumor resection, but long-term follow-up might be needed.

Maxillary sinus lifting procedure and bone grafting are used to reconstruct atrophic maxillae. These procedure are usually followed by the placement of endosseous dental implants. Different materials and techniques can be used for sinus bone grafting. Platelets are known to contain various growth factors involved in the repair of the vasculature and tissues, and it is known that the specialized platelet secretory granules, the alpha granules, contain platelet derived growth factor(PDGF), transforming growth factor-beta(TGF-beta), insuline like growth factor-I(IGF-I), epidermoid growth factor(EGF), and others. This study was to evaluate the effect of PRP on bone formation in a sinus bone grafting. Twelve rabbits were included in this randomized, blinded, prospective pilot study. In experimental group, sinus bone grafting with autobone and platelet rich plasma. In control group, sinus bone grafting with only autobone. Rabbits were sacrificed at 2nd, 4th, 8th, 12th weeks postoperatively. Clinical and radiographic tests, histological analysis were conducted to compare both sides. In clinical examination, there in no significant difference between experimental group and control group. But, in radiographic examination, a distinct incresed in the radiopaque of the PRP experimental group at 2nd and 4th weeks. The histologic examination revealed that more new bone formation and osteoblast activity were seen in experimental group at 2nd and 4th weeks. In conclusion, PRPs action in sinus bone grafting had a capacity of increased new bone formation in a early bone healing stage.

A castrated male, 6 year-old Shih-Tzu, weighing 4.6 kg with a discharge from the external ear canal and a mal-odor was referred to Verterinary Medical Teaching Hospital, Seoul National University. Radiographic findings were narrowing and focal loss of an air density in the left ear canal and bilateral thickening of the osseous bullae. For more detail examination, computed tomography was used. In computed tomographic findings, bilateral thickening of the bulla wall and increased opacity of the bulla space were observed. Thus this dog was diagnosed as bilateral otitis media. Then surgical correction, total ear canal ablation, was performed successfully and the patient showed a good prognosis thereafter. It is considered that computed tomography might serve as an useful imaging tool for otitis media and that it supplies information not obtained with a conventional radiography.

A 16-month old female Golden retriever dog was presented with a 2-week history of left-sided exophthalmos, third eyelid prominence, some scale of the trunk, mild anorexia, mild diarrhea and depression. In radiographic findings, a mass with increased opacity in the left retrobulbar area was observed. Cytologic and histopathologic examinations after enucleation and mass excision showed diffuse round cell accumulation and adjacent small area of elongated cell proliferation were shown. They also illustrated the neoplastic cells with large nucleoli, multiple nucleoli that differ in size and scant cytoplasm with several clear vacuoles. Extent of local invasiveness and central necrosis of the retrobulbar mass was identified by magnetic resonance imaging. Based on the physical and laboratory examination, radiographic, cytologic and histopathologic findings this case was diagnosed as extranodal malignant lymphoma of the retrobulbar area.

A 2.5 kg, three-month-old. intact male Shih-tzu was referred to the Veterinary Teaching Hospital of Kyungpook National University to examine the postoperative inflammation and suspected diaphragmatic defect which had been found during the surgical correction of umbilical hernia by the referral veterinarian. An umbilical hernia had been surgically repaired one month earlier at the time. Radiographic findings were enlarged cardiac silhouette containing soft tissue and gas densities and overlapping of cardiac and diaphragmatic borders. Ultrasonographic findings revealed the discontinuity of the diaphragm and the partial herniation of the liver into the pericardial sac. According to these findings, it was diagnosed as congenital peritoneopericardial diaphragmatic hernia(PPDH). Because the dog showed no serious clinical signs of PPDH and the owner didn't want a surgery to correct it, the dog was discharged the day of the examination after treatment of the inflammatory surgical site. On the follow-up after three months, the dog showed no distinct clinical signs of PPDH and was in good physical condition.

Recently the patient exposure by medical and dental x-ray examination has grown rapidly and diagnostic radiology represents the largest source of man-made radiation. For the patient protection, the principle of justification and optimization should be followed. All the radiographic examinations have to show a potential benefit to the patient weighing against the potential risk. After they are justified, the radiographic exposure should be kept as low as reasonably achievable, taking into account economic and social factors. For the safe use of radiation in dentistry, the radiation safety management in accordance with the legislation is important. The present status and the future of radiation safety management in dental radiology in Korea and other country will be discussed.

Flatfoot is defined as loss of medial arch with hindfoot valgus, but normal condition is obscure due to wide individual variance. Loss or decreasing of medial longitudinal arch with radiographic image is clinically diagnosed as flatfoot. Flatfoot without symptoms is not an indication for treatment. The etiologies of flatfoot are congenital cause, hypermobility, tarsal coalition, neuromuscular disease, post-traumatic deformity, Charcot arthropathy, and posterior tibial tendon dysfuction. The flatfoot is classified as congenital and acquired, flexible, and rigid. The diagnosis is made by physical examination and radiographic findings. In particular, the posterior tibial tendon dysfunction is known as adult acquired flatfoot.

The radiographic diagnosis of osteomyelitis can be suspected early with deep soft tissue swelling, but the actual bone changes of osteomyelitis may be delayed as long as 10 to 14 days after onset or may be totally aborted by antibiotic therapy. Recognition of osteomyelitis by bone imaging is far more rapid than by conventional radiographic examination and can be used on admission to establish the diagnosis. Ten patients suspected of having early, acute osteomyelitis were studied by TC-99m Pyrophosphate bone imaging. Radiographs taken at the same time were all negative. Of these 9 patients showed positive bone images. The bone imaging provides a safe, accurate, noninvasive technique for the early diagnosis of osteomyelitis.
